hi friends,
i have an Web Form named PO.aspx,User makes entry in it and save the records for that particular data.
my requirement is, whenever the Records which was saved previously comes for Update in PO.aspx Web Form and user changes some value in it.
example:
(PO date) Previously old value was '20-07-2012' and after modifying it to '24-07-2012' new value.
then a new record (log) should be maintained in Database table with values like
Username,Oldvalue,Newvalue,UpdatedDate,Comments(Reason for Change).
This should be done for each control in Web Form whose value has been changed by user every time.
how it can be achieved!!!
Regards,
Aamir
